Abstract

The present disclosure relates to compositions comprising at least one carbonaceous particulate material comprised of synthetic graphite particles having a BET specific surface area (SSA) of equal to or less than 4 m2/g, and further comprising between about 5 and about 75% (w/w) of at least one carbonaceous particulate material comprised of natural graphite particles coated with non-graphitic carbon and having a BET SSA of equal to or less than 8 m2/g. Such compositions are particularly useful as active material for negative electrodes in, e.g., lithium-ion batteries and the like in view of their overall favorable electrochemical properties, particularly for automotive and energy storage applications. The present disclosure also relates to the use of said non-graphitic carbon-coated natural graphite particles for preparing compositions that are suitable for being used as an active material in a negative electrode of, e.g., a lithium ion battery. The non-graphitic carbon-coated natural graphite particles described herein are also useful as a carbonaceous additive to increase, e.g., the energy density and charge rate performance of a lithium-ion battery while maintaining the power density of the cell compared to a cell with an anode absent the carbonaceous additive.
